Easy Breathing - Dome Structure keeping a fixed shape and conforming curves make breathing space. Hard shell in the center layer creates a stable shape. So, the mask moves less back and forth while breathing or speaking.
No Ear Pain and No Skin Trouble - The nylon and polyurethane straps are designed to have excellent elasticity, so your ears won't hurt even if you wear them all day long. And the soft fabric material (Polypropylene and Polyethylene) does not cause fluff, so it does not cause troubles on the skin of the face, and there is no discomfort from the lint on the lips.
Comfort Feeling of Wearing - Gently and Securely conforms to the curves of the face to provide a comfortable fit. Mask design suits the shape of the face to make it comfortable to wear and less touch to your lips through maintaining shape
